I have a new DIR628, it has a XP pc and laptop, and Win7 Pc connected to the hard wired ports of the router. I have a WD 1T hard drive connected to the USB port, Have no problems connecting to the HD{being used as a back up HD}. My grandaughter's Win7 Dell laptop connects to the HD ok. My daughters Vista laptop will not connect to the HD, it sees it and says it's avaiable but won't connect. The laptop won't connect wireless or hard wired to the router. I emailed the question to Dlink, but haven't had any feedback. I hope someone on this forum has had the same type of problem and has a answer. Thank you.
